simplify ln((x^2-9)/(x^4))

Solution

simplify

ln (\frac{x ^{2} - 9}{x ^{4}})

Solution

ln (x^{2} - 9) - 4 ln (x)

Solution steps

ln (\frac{x ^{2} - 9}{x ^{4}})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{x ^{2} - 9}{x ^{4}}) = ln (x^{2} - 9) - ln (x^{4})

= ln (x^{2} - 9) - ln (x^{4})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (x^{4}) = 4 ln (x)

= ln (x^{2} - 9) - 4 ln (x)
